Specification of Letters Patent.

Patented Dec. 24, 1907.

Application led January 12, 1906. Serial No. 295,721.

To all 'whom it may concern.'

Be it known that I, ELLswoRTH JOSEPH l EDWARDS, a citizen ofthe UnitedStates, and

a resident of Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and Improved Roller-Bearing, of whichthe following is a full, clear, and exact description.

The object of the invention is to providea new and improved rollerbearing for the hubs of wheels, journals, spindles and the like,arranged to reduce the friction of the working parts to a minimum, totake l up all end thrust, to render the bearing dust-proof, and topermit of readily a plying the roller bearing to different size( axles,journals, spindles, shafts and the like without reconstructing the same.

The invention consists of novel features and parts and combinations ofthe same which will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawingsI forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a sectional side elevation of the improvement as applied tothe hub and axle of a wheel; Fig. 2 is a transverse section of the same,on the line 2-2 of Fig. 1; Fig. 3

is a perspective view of one of the main rollers; Fig. 4 is a like Viewof one of the auxiliary s acing rollers; and Fig. 5 isa similar view o amodified form of the spacing roller. As illustrated in Fig. 1, tworoller bearings, alike in construction, are inter osed between the axle,journal or spindle and the hub B of the wheel, and each roller bearingis provided with alternately arranged main rollers C and auxiliary orspacing rollers D, both sets of rollers having their axes arranged inthe same circular path, as will be readily understood by reference toFig. 2. The bearing boxes for each of the two sets of rollers C and Dconsist of an outer bearing ring E fitted into the hub B and securedthereto by suitable means, and an inner bearing ring made of tworing-shaped members F and F of which the member F contains the member Fand is secured to a sleeve G fastened to the journal or spindle A. Theouter and inner bearingrings E and F, F are concentric and spaced apartfor the main rollers C to contact Withboth rings E and F, and the endsof the said rings E and F, F are formed with beveled shoulders,

said shoulders forming the inner and outer half of annular V-shapedgrooves, each approximately V-shaped in cross section for the conicalends C and D of the rollers C and D to bear against, to thus cause therollers l and D to travel in the same circular path, as above mentioned.

As indicated in Fig. 2, the main rollers C and the auxiliary or spacingrollers D are in peripheral contact with each other, so that vthe mainrollers C rotate the spacing rollers D in an opposite direction, but thespacing rollers D travel in the same annular path as the main rollers C,owing to the ends C and D of the rollers C and D en aging the groovesformed between the shoulders of the bearing rings E and F, F as abovementioned.

The ends ofthe rings E and F, F are sufficiently spaced apart to permitthe use of' spindles D2 formed on the conical ends Dl of the s acingrollers D, if it is desired to use such ro 1ers as shown in Fig. 5.

In order to render the bearing box and the rollers contained thereindust-proof, a dustcap His provided, in the form of a ring, having, atits inner face, an annular groove forl Athe reception of a washer I madeof felt or other material and facing the outer lendl of the bearing box.A retaining ring J, fitted on the sleeve G, rests against the outer endof the bearing box and is provided with an outwardly-extending annularflange J engaging the washer I, so as to hold the same in place. Thering K held on the sleeve G abuts against the retaining ring J, and thisring K, as Well as the dust-proof ca H for the inner roller bearing, isengage by an annular flange A formed on the journal or spindle A, andthe ring K and the dust-proof cap H for the outer roller bearing areengaged by a nut A2 screwingv on the reduced threaded end A3 of thejournal or spindle A. Thus the several parts of each roller bearing aresecurely held in place, and at the same time the roller bearings arerendered completely dust-proof, so as to insure long life thereof.

The outer end of the sleeve G is adapted to receive a bushing L, topermit of conveniently fitting the sleeve G onto journals or spindles Aof tapering or of different sizes, it being understood that in somecases the sleeve G may be entirely dispensed with and the ring F of eachroller bearing fitted directly on the journal or spindle A. As shown inFig. 1, both the hub B and the sleeve G are provided with annularshoulders for engagement by the inner ends of the rings E and F, tolimit the inward movement of the bearing boxes containing the main rol]-ers C and the spacing rollers D.

The detailed construction of the hub B shown in Fig. 1 forms no part ofthis invention, and hence detailed description of the same is not deemednecessary.

The roller bearing shown and described is simple and durable inconstruction, composed of comparatively few parts, not liable to get outof order, and by having the bearing box constructed in the mannerdescribed, the several parts of the roller bearing can be readily andconveniently assembled and placed in position on the device on which theroller bearing is to be used.

Having thus described my invention, I claim as new and desire to secureby `Letters Patentzv 1. A roller bearing having annular groovesapproximately V-shaped in cross section, the bearing being formed of anouter bearing ring and an inner bearing ring, the latter made of tworing-shaped members, one containing the other, a set of main rollershaving conical ends in engagement with the said annular grooves, and aset of spacing rollers having conical ends in engagement with the saidannular grooves, the said spacing rollers' alternating with the saidmain rollers, and the said main rollers and the said spacing rollershaving their axes traveling in the same circular path.

2. A roller bearing having annular grooves approximately V-shaped incross section, the bearing being formed of outer and inner hearingrings, one of said rings being composed of two ring shaped members, onecontaining the other, a set of main rollers having their ends inengagement with said annular grooves, and a set of spacing rollershaving their ends in engagement with said annular grooves, the saidspacing rollers alternating with the said main rollers, and the saidmain rollers and the said spacing rollers having their axes traveling inthe same circular path 3. A roller bearing comprising inner and outerrings having on each end beveled shoulders, the adjacent shoulders ofthe inner and outer rings forming approximately V-shaped annulargrooves, one of said rings being composed of two ring-shaped members,one containing the other, a set of main rollers having their ends inengagement with the said grooves, and a s'et of spacing rollers havingtheir ends in engagement with the said grooves, the said spacing rollersalternating with the said main rollers, and the said main rollers andthe said spaeing rollers having their axes traveling in the samecircular path. n

I n testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
